SAFETY-PIN.

SPECIFICATION forming part of Letters Patent N0. 756,810, dated April 12, 1904. Application filed November 9, 1903. Serial No. 180,403. (No model.)

To all whom it may concern.-

Be it known that I, CHRISTIAN ANDRnsEN, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Safety- Pins, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in safety-pins; and it consists in the novel construction of pin more fully set forth in the specification, and pointed out in the claims.

In the drawings, Figure 1 is a plan of the pin shown in its locked position. Fig. 2 is a combined plan and longitudinal section of the same. Fig. 3 is a transverse section on line 3 3 of Fig. 1. Fig. 4 is a horizontal section on line 4: 4: of Fig. 2, and Fig. 5 is a plan of the blank from which the locking-tongue is formed.

The object of my invention is to construct a safety-pin in which the piercing member or prong can be effectively locked within the sheath or socket by which the point of the prong is received, one in which the lockingtongue shall be carried directly by the body portion or stationary member of the pin, one in which the locking-tongue shall be so disposed on the stationary member as to distribute the strains to which it is subjected to the best advantage, and one possessing further and other advantages better apparent from a detailed description of the invention, which is as follows:

Referring to the drawings, 1 represents the stationary member or body portion of the pin, and 2 the piercing member or prong, the two being connected by means of the resilient coil 3, which tends to normally force the prong to an open position. Secured at one end of the body portion is a sheath 4, having a socket for the reception of the point of the piercing member, said sheath being preferably made of a single piece of metal and being of any prevailing form. The wire of the body portion 1 is continued along the inner wall of the sheath to a point adjacent the free end of the latter, as best shown in Fig. 2.

Secured at a convenient point to the extension of the wire 1 within the sheath and preferably formed of a piece of sheet metal folded about said wire is a flat locking-tongue 5, adapted to enter or engage the eye 6 in the prong, which eye is located at a point adjacent to the point of said prong. This tongue may be secured to the wire 1 in any convenient way, but preferably folded about the same, as shown, the base of the fold being embedded in a depression 7, formed in the wall of the sheathsocket, the walls of this depression serving as abutments for the tongue while subjected to the strains communicated thereto by the prong 2 under any load which the latter is obliged to carry or any draft to which it may be subjected. The tongue is disposed in the plane of the line of draft, as shown, and may be of any shape or configuration or of any available material. This tongue 5 must not be confounded with the terminal hooks or fingers formed on the body-wire in pins of the character here referred to, as these hooks, being part and parcel of the wire, are insecure, tending ,as they do to yield under a strain, and thus rendering the pin useless. With the present construction, however, there is no danger of the tongue flaking ofi, the strain being initially and directly imparted to the body thereof. and also to the shield where the base of the tongue is embedded in a depression, such as 7.

In the locking operation the prong is guided into engagement with the tongue by the guide wall 8 and by the walls of the sheath-socket, within which the point of the prong is receiveol.

Obviously I need not limit myself to the precise details here shown, as they may in a measure be departed from without in any wise affecting the nature or spirit of my invention. Neither do I limit myself to the number of of such bodyportion within the sheath, anddisposed in the plane of the line of draft to which the prong is subjected, substantially as set forth.

2. A safety-pin comprising a body portion, a piercing member or prong connected thereto, a sheath at one end of the body portion for receiving the point of said prong, the latter having an eye located adjacent to the point, and the body portion being extended along the wall of the sheath, and a lockingtongue formed about the extension of such body portion within the sheath, the latter having a suitable depression formed therein for the reception of the base of the tongue, substantially as set forth.

3. A safety-pin comprising a body portion, a piercing member or prong connected thereto, a sheath at one end of the body portion for receiving the point of said prong, the latter having an eye located adjacent to the point, and the body portion being extended along the wall of the sheath, and a lockingtongue composed of an independent piece of sheet metal secured to the extension of such 'body portion within the sheath, and disposed in the plane of the line of draft to which the prong is subjected, substantially as set forth.

In testimony whereof I aflix my signature in presence of two. witnesses.
